BEDSTEAD-FASTENING.

Specication of Letters Patent No. 5,649, dated June 27, 1848.

To all whom it may concern Be it known that I, JAMES C. HELME, ofWilkes-Barre, in the county of Luzerne and State of Pennsylvania, have-invented a new and Improved Beadstead-Fastener; and I do hereby declarethe following to be a full, clear, and exact description thereof,reference being had to the accompanying drawings, making a part of thisspecification, in which* Figure 1 is a perspective view of therespective parts of my bedstead fastener united, and Figs. 2, and 3, areperspective views of the same detached. Figs. 4 and 5, are perspectiveviews of a modification of my improved bedstead fastener.

Fig. 3, represents the form of the portion of my improved bedsteadfastener which is attached to the ends of the rails; it is composed ofthe metallic ring A, having the disk I, in its center, to which it isconnected by the radial clutching arms J, J, the whole being cast in onepiece. The ring A, and disk I, correspond with each other in thickness;the radial clutching arms J, J, are double the thickness of the ring anddisk, the base of the three being on the same plane, and the face of thearms rising above the face of the disk and ring, as represented. Thesides of the radial clutching arms flare outward from their base, sothat the area of their face is about double that of their base. c, is anarm cast with, and projecting from the center of the base of the disk I,having a projecting button head al, upon its eX- tremity. This arm, c,is inserted into a hole in the end of the rails, and is secured thereinas follows: e, e, are strips of wood placed around the shank of the armc, these are immersed in glue previous to inserting the arm in itsreceiving aperture, and the hardening of the glue rmly secures theshanks within the same. This portion of the fastener is kept fromturning by means of screws inserted through the apertures Z, Z, in theclutching arms, into the ends of the rails. s, is a spindle projectingfrom the center of the face of the disk I, with which it is cast. Fig.2, represents the form of the portion of the fastener secured to theposts of the bedstead, the ring B, the disk L, and radial clutching armsK, K, of this portion of the fastener, eXactly correspond in form andproportion with the same parts represented in Fig. 3 and describedabove, save that jecting button head g, at its extremity.

This portion of the fastener is secured to the post by means of thestrips of wood h, it, placed around the arm f, and immersed in glueprevious to inserting the arm in the aperture in the post; and isfurther'secured and prevented from turning by means of the points n, n,projecting from the ears 0, o, and driven into the post, or by screwspassing through apertures in the ears, or through the apertures m, m, inthe clutching arms K, K. I sometimes cast steadying points on the ringsA, and B, to keep 'them from turning, as represented in Fig. l.

The respective portions of the fastener being thus secured to the postsand rails of a bedsted, they are brought together by inserting thespindle s, projecting from the face of the portion of the fastener onthe end of the rail, into the hollow arm f, projecting from the base ofthe portion of the fastener secured to the post, and passing theprojecting face of the radial clutching arms J, J, into the spacebetween the clutching arms K, K, then by turning the rail in eitherdirection, the projecting edges of the clutching arms, on each portionof the fastener, will pass under and lock with each other, asrepresented in Fig. 1, drawing the face of each portion of the fastenerso closely to each other as to render them bug proof. In the face of oneof the rings'A, B, a groove p, is formed, and in the face of the otherring two grooves p, 29, of corresponding size are formed; when therespective portions of the fastener are turned, either to the right orto the left, so as to lock with each other, the grooves p, p, in eachring are brought opposite each other, forming a mortise for thereception of a wedge shaped key r, which secures the respective portionsof the fastener firmly to each other.

In Figs. 4 and 5, the radial clutching arms are of the same form asrepresented in Figs. 2 and 3. The arms Gr, Gr, are cast with a ring D,leaving a space between their inner ends; the arms F, F, are cast with,and project from the face of a disk C; the inner ends of the clutchingarms F, F, are united by a hub E, which accurately fits between theinner ends of the arms G, G, when the respective parts of the fastenerare brought Y quentlyV but one pattern of each portion of the fastenerWill be required to a bedstead.

5 What I claim as my invention and desire to secure by Letters Patent,is

Y The manner of constructing a double right and left hand fastener forsecuring the rails to the posts of bedsteads, by means of the radialclutching arms, combined with metallic disks and rings, and operatingWith each other substantially in the manner herein dey scribed, andrepresented in both modifications of my improved bedstead fastener.
